Yes, while I understand what you are saying, it should also be mentioned that people should be tolerant of those who aren't like them. If I didn't like you "just because you live in KY", I wouldn't be a good canidate for an office would I?
Liking someone has nothing to do with performing a professional task for them. If you're a doctor you are held legally and professionally liable for your actions. If you show too much gross negligence you can even goto jail.
